BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method for treating ocular inflammatory diseases in a subject in need of such treatment, which comprises administering a pharmaceutical composition comprising a therapeutically effective amount of at least one agonist of Formyl peptide receptor 2 (FPR2).

2. Summary of the Related Art

The formyl peptide receptor (FPR) family is involved in host defense against pathogens, but also in sensing internal molecules that may provide signals of cellular dysfunction. This family includes 3 members in humans and one member of this family FPR2 (also known as FPRL-1, ALXA4) is a G protein-coupled receptor that is expressed predominantly on inflammatory cells such as monocytes and neutrophils, as well as on T cells and has been shown to play a critical role in leukocyte trafficking during inflammation and human pathology (Chiang N, Serhan C N, Dahlen, S, Drazen J M, Hay D W P, Rovati E, Shimizu T, Yokomizo T, Brink, C. The lipoxin receptor ALX: Potent ligand-specific and stereoselective actions in vivo. Pharmacological Reviews 2006; 58: 463-519). FPR2 is an exceptionally promiscuous receptor that responds to a large array of exogenous and endogenous ligands, including serum amyloid A (SAA), chemokine variant sCKβ8-1, the neuroprotective peptide humanin, anti-inflammatory eicosanoid lipoxin A4 (LXA4) and glucocotricoid-modulated protein annexin A1 (Chiang N, Serhan C N, Dahlen, S, Drazen J M, Hay D W P, Rovati E, Shimizu T, Yokomizo T, Brink, C. The lipoxin receptor ALX: Potent ligand-specific and stereoselective actions in vivo. Pharmacological Reviews 2006; 58: 463-519). FPR2 transduces anti-inflammatory effects of LXA4 in many systems, and has been shown to play a key role in the resolution of inflammation (Dufton N, Perretti M. Therapeutic anti-inflammatory potential of formyl peptide receptor agonists. Pharmacology & Therapeutics 2010; 127: 175-188). FPR2 knockout mice show exaggerated inflammation in disease conditions as expected by the biological role of the receptor (Dufton N, Hannon R, Brancaleone V, Dalli J, Patel H B, Gray M, D'Aquisto F, Buckingham J C, Perretti M, Flower R J. Anti-inflammatory role of the murine formyl-peptide receptor 2: Ligand-specific effects on leukocyte responses and experimental inflammation. Journal of Immunology 2010; 184: 2611-2619).

Activation of FPR2 by lipoxin A4 or its analogs and by Annexin I protein has been shown to result in anti-inflammatory activity by promoting active resolution of inflammation which involves inhibition of polymorphonuclear neutrophils (PMNs) and eosinophils migration and also stimulate monocyte migration enabling clearance of apoptotic cells from the site of inflammation in a nonphlogistic manner (Maderna P, Cottell D C, Toivonen T, Dufton N, Dalli J, Perretti M, Godson C. FPR2/ALX receptor expression and internalization are critical for lipoxin A4 and annexin-derived peptide-stimulated phagocytosis. FASEB 2010; 24: 4240-4249; Reville K, Cream J K, Vivers S, Dransfield I, Godson C. Lipoxin A4 redistributes Mysoin IIA and Cdc42 in macrophages: Implications for phagocytosis of apoptotic leukocytes. Journal of Immunology 2006; 176: 1878-1888). In addition, FPR2 has been shown to inhibit NK cytotoxicity and promote activation of T cells which further contributes to down regulation of tissue damaging inflammatory signals. FPR2/LXA4 interaction has been shown to be beneficial in experimental models of ischemia reperfusion, angiogenesis, ocular inflammation such as endotoxin-induced uveitis, and corneal wound healing (Serhan C.

Endogenous LXA4 circuits are determinants of pathological angiogenesis in response to chronic injury. American Journal of Pathology 2010; 176: 74-84; Gronert K. Lipoxins in the eye and their role in wound healing. Prostaglandins, Leukotrienes and Essential fatty Acids. 2005; 73: 221-229). Pharmaceutical utility of lipoxin A4 and its analogs are hampered by inherent physicochemical properties of the natural poly-olefinic natural product. Therefore, small molecule anti-inflammatory agonists of FPR2 would have a wide variety of therapeutic benefit in inflammatory disorders especially in the eye. Targeting FPR2 selectively would also have benefits of reduced side effects as compared to more broad acting anti-inflammatories such as steroids or NSAIDs which have significant side effects of elevated IOP and delays in wound healing in the eye. FPR2 is also expressed in ocular tissues in the cornea and also the posterior of eye, in addition to the inflammatory cells that migrate into the ocular tissues. FPR2 thus represents an important novel pro-resolutionary molecular target for the development of new therapeutic agents in ocular diseases with excessive inflammatory responses.

Such methods can be performed, for example, by administering to a subject in need thereof a therapeutically effective amount of at least one compound of the invention, or any combination thereof, or pharmaceutically acceptable salts, hydrates, solvates, crystal forms and individual isomers, enantiomers, and diastereisomers thereof.

The actual amount of the compound to be administered in any given case will be determined by a physician taking into account the relevant circumstances, such as the severity of the condition, the age and weight of the patient, the patient's general physical condition, the cause of the condition, and the route of administration.

The patient will be administered the compound orally in any acceptable form, such as a tablet, liquid, capsule, powder and the like, or other routes may be desirable or necessary, particularly if the patient suffers from nausea. Such other routes may include, without exception, transdermal, parenteral, subcutaneous, intranasal, via an implant stent, intrathecal, intravitreal, topical to the eye, back to the eye, intramuscular, intravenous, and intrarectal modes of delivery. Additionally, the formulations may be designed to delay release of the active compound over a given period of time, or to carefully control the amount of drug released at a given time during the course of therapy.

In another embodiment of the invention, there are provided pharmaceutical compositions including at least one compound of the invention in a pharmaceutically acceptable carrier thereof. The phrase “pharmaceutically acceptable” means the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof.

Pharmaceutical compositions of the present invention can be used in the form of a solid, a solution, an emulsion, a dispersion, a patch, a micelle, a liposome, and the like, wherein the resulting composition contains one or more compounds of the present invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for enteral or parenteral applications. Invention compounds may be combined, for example, with the usual non-toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used include glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea, medium chain length triglycerides, dextrans, and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form. In addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. Invention compounds are included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or disease condition.

Pharmaceutical compositions containing invention compounds may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of a sweetening agent such as sucrose, lactose, or saccharin, flavoring agents such as peppermint, oil of wintergreen or cherry, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets containing invention compounds in admixture with non-toxic pharmaceutically acceptable excipients may also be manufactured by known methods. The excipients used may be, for example, (1) inert diluents such as calcium carbonate, lactose, calcium phosphate or sodium phosphate; (2) granulating and disintegrating agents such as corn starch, potato starch or alginic acid; (3) binding agents such as gum tragacanth, corn starch, gelatin or acacia, and (4) lubricating agents such as magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed.

In some cases, formulations for oral use may be in the form of hard gelatin capsules wherein the invention compounds are mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin. They may also be in the form of soft gelatin capsules wherein the invention compounds are mixed with water or an oil medium, for example, peanut oil, liquid paraffin or olive oil.

Pharmaceutical compositions containing invention compounds may be in a form suitable for topical use, for example, as oily suspensions, as solutions or suspensions in aqueous liquids or nonaqueous liquids, or as oil-in-water or water-in-oil liquid emulsions.

Pharmaceutical compositions may be prepared by combining a therapeutically effective amount of at least one compound according to the present invention, or a pharmaceutically acceptable salt thereof, as an active ingredient with conventional ophthalmically acceptable pharmaceutical excipients and by preparation of unit dosage suitable for topical ocular use. The therapeutically efficient amount typically is between about 0.001 and about 5% (w/v), preferably about 0.001 to about 2.0% (w/v) in liquid formulations.

For ophthalmic application, preferably solutions are prepared using a physiological saline solution as a major vehicle. The pH of such ophthalmic solutions should preferably be maintained between 4.5 and 8.0 with an appropriate buffer system, a neutral pH being preferred but not essential. The formulations may also contain conventional pharmaceutically acceptable preservatives, stabilizers and surfactants. Preferred preservatives that may be used in the pharmaceutical compositions of the present invention include, but are not limited to, benzalkonium chloride, chlorobutanol, thimerosal, phenylmercuric acetate and phenylmercuric nitrate. A preferred surfactant is, for example, Tween 80. Likewise, various preferred vehicles may be used in the ophthalmic preparations of the present invention. These vehicles include, but are not limited to, polyvinyl alcohol, povidone, hydroxypropyl methyl cellulose, poloxamers, carboxymethyl cellulose, hydroxyethyl cellulose cyclodextrin and purified water.

Tonicity adjustors may be added as needed or convenient. They include, but are not limited to, salts, particularly sodium chloride, potassium chloride, mannitol and glycerin, or any other suitable ophthalmically acceptable tonicity adjustor. Various buffers and means for adjusting pH may be used so long as the resulting preparation is ophthalmically acceptable. Accordingly, buffers include acetate buffers, citrate buffers, phosphate buffers and borate buffers. Acids or bases may be used to adjust the pH of these formulations as needed. In a similar manner an ophthalmically acceptable antioxidant for use in the present invention includes, but is not limited to, sodium metabisulfite, sodium thiosulfate, acetylcysteine, butylated hydroxyanisole and butylated hydroxytoluene.

Other excipient components which may be included in the ophthalmic preparations are chelating agents. The preferred chelating agent is edentate disodium, although other chelating agents may also be used in place of or in conjunction with it.

The ingredients are usually used in the following amounts:

Ingredient Amount (% w/v) active ingredient about 0.001-5 preservative   0-0.10 vehicle   0-40 tonicity adjustor   0-10 buffer 0.01-10 pH adjustor q.s. pH 4.5-7.8 antioxidant as needed surfactant as needed purified water to make 100%

The actual dose of the active compounds of the present invention depends on the specific compound, and on the condition to be treated; the selection of the appropriate dose is well within the knowledge of the skilled artisan.

The ophthalmic formulations of the present invention are conveniently packaged in forms suitable for metered application, such as in containers equipped with a dropper, to facilitate application to the eye. Containers suitable for dropwise application are usually made of suitable inert, non-toxic plastic material, and generally contain between about 0.5 and about 15 ml solution. One package may contain one or more unit doses. Especially preservative-free solutions are often formulated in non-resealable containers containing up to about ten, preferably up to about five units doses, where a typical unit dose is from one to about 8 drops, preferably one to about 3 drops. The volume of one drop usually is about 20-35 μl.

The pharmaceutical compositions may be in the form of a sterile injectable suspension. This suspension may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides, fatty acids (including oleic acid), naturally occurring vegetable oils like sesame oil, coconut oil, peanut oil, cottonseed oil, etc., or synthetic fatty vehicles like ethyl oleate or the like. Buffers, preservatives, antioxidants, and the like can be incorporated as required.

The compounds of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions may be prepared by mixing the invention compounds with a suitable non-irritating excipient, such as cocoa butter, synthetic glyceride esters of polyethylene glycols, which are solid at ordinary temperatures, but liquefy and/or dissolve in the rectal cavity to release the drug.

Since individual subjects may present a wide variation in severity of symptoms and each drug has its unique therapeutic characteristics, the precise mode of administration and dosage employed for each subject is left to the discretion of the practitioner.

The compounds and pharmaceutical compositions described herein are useful as medicaments in mammals, including humans, for treatment of diseases and/or alleviations of conditions which are responsive to treatment by agonists or functional antagonists of FPR2. Thus, in further embodiments of the invention, there are provided methods for treating a disorder associated with modulation of FPR2. Such methods can be performed, for example, by administering to a subject in need thereof a pharmaceutical composition containing a therapeutically effective amount of at least one invention compound. As used herein, the term “therapeutically effective amount” means the amount of the pharmaceutical composition that will elicit the biological or medical response of a subject in need thereof that is being sought by the researcher, veterinarian, medical doctor or other clinician. In some embodiments, the subject in need thereof is a mammal. In some embodiments, the mammal is human.

Materials and Methods

FPR2 agonists would be expected to have significant effects in many different types of ocular inflammation, but have been exemplified by demonstrating anti-inflammatory activity in endotoxin-induced uveitis in rats (FIGS. 1 and 2). Anti-inflammatory activity in this model has been exemplified with the FPR2 agonists described in Table 4.

FLIPR:

HEK-Gα16 cells stably expressing the human FPR2 receptor was utilized. Cells were plated into 384-well poly-D-lysine coated plates at a density of 18,000 cells per well one day prior to use. The growth media was DMEM medium supplemented with 10% fetal bovine serum (FBS), 1% antibiotic-antimycotic, 50 μg/ml hygromycin, and 400 μg/ml geneticin. On the day of the experiment, the cells were washed twice with Hank's Balanced Salt Solution supplemented with 20 mM HEPES (HBSS/hepes buffer). The cells were then dye loaded with 2 μM Fluo-4 diluted in the HBSS/Hepes buffer and incubated at 37° C. for 40 minutes. Extracellular dye was removed by washing the cell plates four times prior to placing the plates in the FLIPR (Fluorometric Imaging Plate Reader, Molecular Devices). Ligands were diluted in HBSS/Hepes buffer and prepared in 384-well microplates. Data for Ca⁺² responses were obtained in relative fluorescence units.

Immunohistochemistry:

Chromagenic DAB immunohistochemistry with antibodies specific to FPR2 was used to determine localization in normal human, primate, and rat eyes. Anti-FPR2 antibody (Abcam) was used at a dilution of 1:200 to detect FPR2 protein in all species.

Endotoxin-Induced Uveitis in Rats:

Uveitis is a harmful ocular inflammatory condition in humans. Anterior uveitis is a recurrent inflammatory disease and may have potentially blinding consequence. The pathogenesis of the disease is poorly understood, and the anti-inflammatory therapy used is non-specific and is associated with significant complications. Animal models are key to understanding the disease and testing novel therapies. A single low dose of lipopolysaccaride (LPS) in the footpad induces anterior uveitis in rats. This model known as endotoxin-induced uveitis serves as a useful paradigm of human anterior uveitis. Male Lewis rats (260±25 grams) were purchased from Charles River Laboratory. Rats were footpad-injected (hind left side) with 100 μl of 1 mg/ml LPS (List Biological Labs) solution (in sterile 0.9% saline). Test compounds were formulated in the vehicle consisting of sodium phosphate, dibasic heptahydrate, salts, CMC and sterile water. Compounds were topically (0.1-1%) or subcutaneously (10 mg/kg) dosed 2 hr after LPS. Animals were sacrificed at 24 hours following LPS injection. Aqueous humor was collected and analyzed to determine inflammatory cell counts and total protein concentrations.

Alkali Burn in Rabbits:

Corneal epithelium plays an important role in the maintenance of corneal function and integrity. Prolonged corneal epithelial defects causes corneal opacity, neovascularization, bacterial infection and visual loss. Corneal epithelial healing is a complex process involving inflammatory response to injury, cell proliferation and migration. Animal models of corneal injury are every useful to test new anti-inflammatory and pro-wound healing therapies. New Zealand White rabbits weighing between 2.1 and 2.5 kg were anesthetized systemically with Ketamine/Xylazine (35/5 mg/kg) subcutaneously and topically with proparacaine (0.5%). The corneal epithelial wound in one eye was induced with a NaOH saturated filter paper containing 1.0 N NaOH for 30 seconds. The eyes were rinsed with sterile PBS. The corneal wound was confirmed by fluorescein staining with 10% sodium fluorescein (Science Lab Com) and slit lamp photography. Test compounds were formulated in the vehicle described above. For initial studies compounds were topically dosed three times a day. Quantification of corneal wound areas was done using Image J software where fluorescing stain green part was traced and converted to total pixel.

The compounds below would be expected to have significant effects in many different types of ocular inflammation, but have been exemplified by demonstrating anti-inflammatory activity in endotoxin-induced uveitis in rats (FIGS. 1 and 2). Anti-inflammatory activity in this model has been exemplified with the following FPR2 agonists:

In this model the compounds show a strong anti-inflammatory activity in blocking the infiltration of neutrophils and protein into the anterior chamber. In addition FPR2 agonists show accelerated healing and re-epithelialization in mouse models of corneal wound as exemplified by compound {[(2S,3S)-2-{[(4-bromophenyl)carbamoyl]amino}-3-methylpentanoyl]amino}acetic acid in (FIG. 3). These data demonstrate that FPR2 agonists are potent and efficacious anti-inflammatory agents suitable for ocular use in different models of ocular inflammation.
